A damping valve includes a valve body has at least one through-flow channel for each flow direction of a damping medium through the valve body. Each through-flow channel connects an inlet to an outlet. a valve disk covers the through-flow channels at the outlet opening the valve disk has a first volume flow of the damping medium through the valve body, at least one pre-orifice in the valve disk and at least one pre-orifice throttle arrangement is arranged at least indirectly adjoining the valve disk and adapted to at least partially cover or open the pre-orifice depending on the flow direction of a damping medium. The pre-orifice throttle arrangement includes multiple structural component parts arranged coaxial to one another, at least two of the structural component parts are inseparably connected to one another.

A preloading device for a piston valve of a vibration damper includes a spring element which is fitted by an inner diameter onto a radially inner centering device which serves for inner centering of the spring element in the installed state of the preloading device. To provide a preloading device for a piston valve by which a reliable inner centering of a spring element can be ensured but which can be placed with low expenditure on assembly at the same time, the spring element is axially fixed at the centering device via retaining means in that the retaining means at least partially enclose the spring element axially on both sides and are rigidly connected to the centering device in each instance.

Damping valve comprising a damping valve body with a through-channel system, which is covered on at least one outlet side by a number of valve disks, where a nonreturn valve disk releases an advance cross section when the damping medium is flowing in one direction and closes off that cross section when the damping medium is flowing in the other flow direction, and where a cover disk with at least one cross section which can be actuated by the nonreturn valve disk limits the lifting movement of the nonreturn valve disk, and where a second cover disk limits the lifting movement of the nonreturn valve disk in the direction opposite that in which the first cover disk works.
